Patent DE-3907702-A1 (DE)
Title: Drawing tool for forming sheets
Inventor: HEHL KARL
IPC: B21D24/14
Filed: 1989-03-10
Abstract: A hydraulic unit of the drawing tool is composed of a working piston (12) carrying the drawing punch (17), an annular piston (13) enclosing said working piston, and a cylinder housing (10) enclosing said annular piston. By means of the hydraulic unit, the driving travel, required for the drawing process, of the driving device (54) of the drawing tool can be converted into a greater drawing travel of the drawing punch (17), in which during the drawing process pressure medium is displaced from a cylinder space (48) bounding the annular piston (13), which drives the working piston (12). For a horizontal drawing direction, the drawing tool can be clamped onto the mould supports (73, 74) of a plastics injection moulding machine, in which case working piston (12) and annular piston (13) can be supplied with pressure medium from cylinder spaces (51, 52; 48) which are spatially separated from one another but interconnectable via a connecting conduit (20). By means of such a design, it is achieved that even heavy drawn parts can be manufactured and the production costs can nevertheless be considerably reduced since the drawing tool can be operated, thanks to its space-saving construction, in the mould-closing unit of a plastics injection moulding machine (Fig. 1).   <IMAGE>

Title: Sepn. of metal from e.g. rock, slurry or liq. waste - involves turbulent mixing of ground material with water and solvent with dissolved metal then passing through sieve
Inventor: MUELLER ALEXANDER
IPC: B01D11/02
Filed: 1989-11-01
Abstract: Separation of metal from rock, slurry, liquid waste or ash using a water and solvent mixture has the novelty of having the metal-containing material ground into a mealy consistency which is then mixed with water and a flow-improving lubricant. The resulting mixture is then fed under pressure against a high-pressure stream of water and solvent so that the mixture is fully wetted. The stream and the mixture are then set into turbulence with one antoehr and fed through a sieve which only permits liquid with dissolved metal particles to pass through it. The metal particles dissolved in the liquid are then deposited via electrolysis. ADVANTAGE - The separation technique is designed to be simple, economic and effective.

Patent DE-4024290-A1 (DE)
Inventor: WULFF GUENTER
IPC: B01J20/281
Filed: 1990-07-31
Abstract: Soft polymer gels often have outstanding separating properties as the stationary phase in chromatography. Their drawback is their low pressure stability. In order to make them useful for efficient, fast separation the column filling must be made pressure-stable. Pressure-stable column fillings may be obtained as mixed bed columns of two different components. A process for producing them is described. To this end, mixtures of the polymer gel responsible for the separating properties with non-porous or porous particles of pressure-stable, inert inorganic or organic materials are used. Such mixed bed columns are pressure-stable and can be used even with small particle diameters and high pressures for liquid, gel permeation or affinity chromatography.

Title: Rail guided hoist with powered lifting gear - has twin lifting chains driven by sprockets on common shaft with one sprocket in advance by 52 deg.
Inventor: FINZEL MANFRED
IPC: B66C11/06
Filed: 1991-02-19
Abstract: The hoist consists of a carriage supported by wheels on the bottom flange of an I-beam, a cross-mounted shaft with spaced chain sprockets over which are guided twin lifting chains connected to the ends of a house beam, and an electric motor drive to the cross-mounted shaft and chain sprockets. Because the four-pocket sprockets (34, 34') are polygonal the chain and load velocity are cylically variable, so that large and damaging vibrations may be induced in the hoist structure. The amplitude of velocity variation at the hook is reduced and the frequency of variation raised above the natural frequency of the structure. By fixing one sprocket angularly in advance of the other by 52 deg. USE/ADVANTAGE - Vibration during lifting is minimised.
